Materials and methods for coating an electrochemically active electrode material for use in a lithium-ion battery are provided. In one example, an electrochemically active electrode material comprises: a polymer coating applied directly to an exterior surface of the electrochemically active electrode material; a metal plating catalyst adhered to the continuous polymer; and a continuous metal coating that completely covers the metal catalyst and continuous polymer coating. The electrochemically active electrode material may comprise a powder comprising one or more secondary particles, and the polymer and metal coatings may be applied to exterior surfaces of these secondary particles.
An electrochemically active electrode material, comprising:
A coated electrochemically active electrode powder, comprising:
A battery cell, comprising an electrode, the electrode comprising a coated electrochemically active electrode material, the coated electrochemically active electrode material comprising powder particles having a continuous polymer coating coupled directly to an exterior surface of the powder particles, a continuous metal coating that completely covers the continuous polymer coating, and a metal catalyst adhered to the continuous polymer coating for catalyzing an electrodeless deposition (ELD) reaction, wherein the continuous polymer coating is positioned between the continuous metal coating and the exterior surface of the powder particles, and the metal catalyst is positioned between the continuous polymer coating and the continuous metal coating.
A method for metallizing a powder particle of an electrochemically active electrode material, comprising:
A coated electrochemically active electrode powder, comprising:
